Overrides:

setSalt in class EncryptionVerifier

setEncryptedVerifier

protected void setEncryptedVerifier(byte[] encryptedVerifier)

Overrides:

setEncryptedVerifier in class EncryptionVerifier

setEncryptedVerifierHash

protected void setEncryptedVerifierHash(byte[] encryptedVerifierHash)

Overrides:

setEncryptedVerifierHash in class EncryptionVerifier

setEncryptedKey

protected void setEncryptedKey(byte[] encryptedKey)

Overrides:

setEncryptedKey in class EncryptionVerifier

addCertificate

public void addCertificate(java.security.cert.X509Certificate x509)

getCertificates

public java.util.List<AgileEncryptionVerifier.AgileCertificateEntry> getCertificates()

clone

public AgileEncryptionVerifier clone()
                              throws java.lang.CloneNotSupportedException

Overrides:

clone in class EncryptionVerifier

Throws:

java.lang.CloneNotSupportedException

getKeySize

public int getKeySize()

The keysize (in bits) of the verifier data. This usually equals the keysize of the header, but only on a few exceptions, like files generated by Office for Mac, can be different.

Returns:

the keysize (in bits) of the verifier.

getBlockSize

public int getBlockSize()

The blockSize (in bytes) of the verifier data. This usually equals the blocksize of the header.

Returns:

the blockSize (in bytes) of the verifier,

setKeySize

protected void setKeySize(int keyBits)

Sets the keysize (in bits) of the verifier

Parameters:

keyBits - the keysize (in bits)

setBlockSize

protected void setBlockSize(int blockSize)

Sets the blockSize (in bytes) of the verifier

Parameters:

blockSize - the blockSize (in bytes)

setCipherAlgorithm

protected final void setCipherAlgorithm(CipherAlgorithm cipherAlgorithm)

Overrides:

setCipherAlgorithm in class EncryptionVerifier
